we have never revoked on a single result. we have revoked on a pattern
thin evidence
i have watched this standard hold for three years including when it was inconvenient for a popular supplier
thats evidence
quick one is the verification log the same thing as a recommendation
both numbers go in
two labs a point or two apart on one lot is normal. both go in the log with both numbers
somebody once offered to fund the testing programme in exchange for an entry. the offer is in the log
has verification ever been reinstated after a revocation
who decides, the mods or the room
pattern not one result
quick one a supplier improving shows in the log as later entries, not as earlier entries being edited
how does a supplier get verification revoked

how long does a verification stay current before it needs refreshing
we refresh on new evidence, not on a clock. an old verification with no recent results says so on the entry
what happens to the log entry when a supplier improves
not a recommendation
a lot number mismatch between the vial and the certificate is a serious finding. post it with photos of both
the lot number on the certificate does not match my vial, what now
refresh on evidence
blinded submissions carry more weight because they remove a variable, not because we distrust the labs
verification is not a recommendation. it means the evidence standard has been met, nothing more
what does not count: the supplier certificate alone, a screenshot, a referral link, or a friend who says it was fine
never for sale
sorry to jump in what counts: an independent report, on a lot you bought yourself, with the lot number, from a lab the room recognises
post the photos
two labs disagree on the same lot, which one goes in the log
Verification log updated: SWB — evidence added, status unchanged.
for the archive the mods maintain the log. the room supplies the evidence and argues about it, which is the correct division, n of 1 obviously
log it either way
slightly off topic but is a screenshot of a report ever acceptable
verification has never been for sale and never will be. offers get posted publicly with the sender redacted
a referral link is disqualifying because it makes the reporter an interested party. that is all
if you want to help, buy a lot, test it, and post the report with the lot number. that is the whole contribution, for what its worth
what actually counts as evidence for a verification
does a good result from VendorInvestigate outweigh a bad one from PeptideMeter
[edited]unrelated but update from 3 months ago: SGN added evidence and the entry now reflects it
